Abstract :
This paper considers optimal power distribution among transmitted symbols relayed by cooperating users in wireless network cocast (WNC) to minimize aggregate transmit power using geometric programming based only on long-term fading statistics or network topology while guaranteeing a predetermined quality of service (QoS). Results show that the proposed scheme can significantly save energy consumption.
